SELF-HEATING FLAT-IRON.

Specification of Letters Patent.

Application filed April 18, 1910. Serial No. 556,207.

To all whom it may concern:

Be it known that I, REINHARD HILDE- BRAND, a citizen of Germany, residing at Milwaukee, in the county of Milwaukee and the State of lVisconsin, have invented a new and useful Improvement in Self-Heating Flat-Irons, of which the following is a specification.

My invention relates to improvements in self-heating fiat irons and has for its object to provide a flat iron, with a fuel receptacle attached to and movable with respect to the main body portion of the iron, said receptacle being adapted to extend beneath the main body portion of the iron when the latter is inverted, and to be filled with liquid fuel, such as alcohol or a similar fuel, which will heat the iron when ignited.

In the accompanying drawings Figure 1 is a plan view of an iron constructed in accordance with my improvements, with the handle removed; Fig. 2, a view in vertical longitudinal section taken through the center of Fig. 1, and showing the handle in elevation; Fig. 3, a view in transverse vertical section of the iron shown in Fig. 1, taken through the transverse center of said Fig. 1; Fig. 1, a lan view of an'iron constructed in accorc ance with my improvements, and showing my preferred form, with the handle in elevation; Fig. 5, a view in vertical longitudinal section, taken through the center of Fig. 4, and showing the fuel receptacle or cap in full lines with its outer rim in engagement with the main body portion of the iron, and forming a closed, asbestos lined cover for the latterand showing the fuel receptacle in broken lines with the outer rim out of engagement with the main body portion of the iron and in position to contain fuel and admit air between the rim and main body portion the handle being shown in elevation in raised position in full lines, and in lowered position in broken lines; and Fig. 6, a View in transverse vertical section, taken through the center of Fig. 1, showing the handle in elevation.

In Figs. 1, 2, and 3, a represents the main body port-ion of a flat iron, 6 a fuel receptacle or cap, 0 a separator or distance piece, by which the cap 7) is held in position with respect to the main body portion of the flat iron, with the outer rim of the cap or fuel receptacle out of contact with said body portion and in position to provide an unobstructed space between the outer rim and the main body portion of the iron throughout the entire circumference of the cap or fuel receptacle, for admitting air to the fuel contained in the receptacle when the iron is in inverted position. The handle d shown in Fig. 2, may be removed by lifting the knob e, and simultaneously the wedge f, both being fastened to a spring g, which is shown as riveted at the point indicated by the reference letter h to the handle cl. The handle is thus adapted to be removed when the iron is to be heated. The iron may then be inverted, in which position the cap or fuel receptacle will be beneath the main body portion of the iron, with an unobstructed space between the rim of the fuel receptacle and the main body portion of the iron throughout the entire circumference of the outer rimthe fuel receptacle or pan and the main body portion of the iron being connected wholly by means of a central distanoe piece or stem 0, so as to leave the entire outer circumference of the receptacle or cap entirely unobstructed for freely ad mitting air to the fuel. The pan or receptacle may then be filled with alcohol or other liquid fuel, which, after being ignited will burn along the whole circumference of the flat iron and fuel receptacle, thereby heating the flat iron. The iron, after being heated, is turned right side up, ready for use, in which position the cover formed by the fuel receptacle or cap, serves to reduce the radiation or loss of heat.

The loss of heat or radiation of heat from the main body portion of the flat iron is reduced to a minimum by constructing the cap or fuel receptacle and main body portion of the iron as shown in Figs. 4:, 5, and 6, and as hereinafter described, in which preferred form the cover is lined with asbestos and forms a closed chamber above the main body portion of the iron when the latter is upright.

In a flat iron constructed as shown in Figs. 4, 5, and 6, a represents a fiat iron, b a cap resting on the flat iron a. The cap b has an outer and an inner rim i and 7c respectively, and is lined with asbestos indicated by t. A bolt m with fiatted head n and shoulder 0 fits loosely through a holedrilled through the flange p which is a part of the cap b. The bolt m is driven tight or screwed into the fiat iron a. A handle d is pro- Iatented Nov. 11, 1911.

vided, which by means of two round spring wires 9, inserted in two holes drilled in the bolt head a can be swung upward to a position suitable for ironing, and down ward to the position indicated in broken lines in Fig. 5, in order to enable the iron to be supported in inverted position with the fuel receptacle beneath the main body portion and in position to contain liquid fuel. The position shown in full lines in Figs. l, 5, and (3 represents a position suitable for ironing. In order to heat the iron the han dle will be swung to the position shown in broken lines in Fig. 5, and the whole iron is laid upside down on the table, resting on the flat surface of a suitable supporting element, such as the bolt head a. The cap Z) will then come into the position shown in broken lines in Figs. 5 and 6, so that when the iron is inverted the cap will rest on the bolt head a. The cap Z) forms a. pan to be filled with alcohol or similar fuel. After igniting the alcohol, the fuel will burn along the whole outer circumference of the rim 7a, and all over the surface of the alcohol in the pan, and also along the whole inner circumference of the rim 2'. Air is admitted to the inner part of the flame through. the holes 7" and .9 located in the center of the cap. The flame is so dis tributed as to enable the Hat iron a to be heated throughout. An asbestos lining If is desirable although it is not indispensable, as it acts as a wick while the flat iron is heated, and acts as a protector against loss of heat while ironing, that is, when the cap is resting on the flat iron a.

I claim 1. A flat iron comprising in its construction a main body portion, a cap provided with an outer rim forming a chamber in the cap for containing liquid fuel, and a stem connected with the central portion of the cap and with the main body portion of the flat iron, for holding the cap in position with respect to the latter.
